Ezekiel 10:1-2

Young's Literal Translation

10 And I look, and lo, on the expanse that [is] above the head of the cherubs, as a sapphire stone, as the appearance of the likeness of a throne, He hath been seen over them.

² And He speaketh unto the man clothed with linen, and saith, `Go in unto the midst of the wheel, unto the place of the cherub, and fill thy hands with coals of fire from between the cherubs, and scatter over the city.' And he goeth in before mine eyes.
